Sir Francis Winnington (7 November 1634 – 1 May 1700) was an English lawyer and politician who sat in the House of Commons at various times between 1677 and 1698. He became Solicitor-General to King Charles II.
Winnington entered the Middle Temple in 1656 and was called to the bar in 1660 and rose steadily, serving as counsel in various Parliamentary impeachments. In January 1672, he became attorney-general to the king's brother, the Duke of York and was knighted on 16 December 1672. He was appointed as Solicitor General in 1675 and chosen as MP for Windsor at a by-election to the Cavalier Parliament in 1677 on the King's recommendation.
During the hysteria of the Popish Plot, Winnington's allegiances changed, and he participated in impeaching the Lord Danby. This led to his dismissal as Solicitor General. However he was elected as MP for Worcester in 1679 (twice) and again in 1681. While Parliament was not sitting, he defended political allies in the court and also the city he represented when its corporation was attacked by Quo warranto proceedings, as well as Oxford. His legal services remained in demand in the reign of James II of England. He was elected as MP for Tewkesbury in 1689, 1692 and 1695, though he had not initially sought the seat.
Winnington married first Elizabeth Herbert of Powick, he had a daughter Elizabeth who married in 1676 Richard Dowdeswell of Bushbury MP, his colleague in the representation of Tewkesbury.
